folders and files 1

[secondleft]

Hi,

Can you show me the code to list all sub-folders and files under a given folder?
Better not use recursive program but if this way is simpler then it is OK.

Thank you in advance.

You can use File class to do this.

Quick and dirty and not checked (should work somewhat like this):

File file = new File(YOUR_PATH);

String[] list = file.list(); // Returns list of files as string array

Check File in die API

Thank you.

How about the sub-folders? Will they be listed in the String array? If they will, how to tell which is file and witch is fub-folder?

You can use the isDirectory() or isFile() methods to check for file or folder.

Actually listFiles() will work better than list() because it will return an array of File, which you can then use.

Thanks a lot! I think those are what I need to make my code.

The most efficient way to list all files and subfolders, and files in those subfolders is to use recursion.

Look at the File API documentation (isFile(), isDirectory() calls)
